I'm still not really sure if _board_ init is the right place ... I feel
more like some _arch_ init.

But I would accept it here for getting the first SPL in at91. We need to
rework that whole arch vs. board related init anyways, so we could
change it then (and insisting on that _now_ would definitely break the
release date).

To say it clear, for this patch no change requested.
